or at least to such an extent as would. cause bursting of the loop, and this continued pressing of the needle beard also has the effect of passing.r the needle through the loop with the least possible resistance.

The outer presser ring may he formed in sections, or elements having beard iressing surfaces may be arranged in a circ e about the needle row.

The inner presser' wheel or member v7 is mounted on a pin 13 of a support. 14 depending from an arehshaped arm 15 pivoted at 1G to a bracket 17 adjustahly held by a screw 18 passing through a slot 19 of the bracket into the cap 20 which incloscs the .knitting elements. as will be made clear hereinafter. This cap is held in place by latches 20 pivoted on pins 20" beneath the ring 57 and locked in place by springs 20 which have projections entering openings in the latches. The springs also serve to hold the latches on their pivots, The arm 1.5 at its free end is locked in position by a latch 21 pivoted on the screw 22 passing through the bracket 2 into the cap or cover 20. The free end of the arm 15 lits in a notch 24 of theI bracket 23, Figs. 1 and 3, and the latchv works transverselythrough a notch or slot 25 in the bracket and a notch 26 in the end of the arm.

The latch is notched at 27 and when turned by pressure on the linger piece oi" projection 2S, Fig. 3, this nogh 27 is brought into line with the free end o `the arm 15 and said arm may then be lifted, withdrawing the presser'wheel 7 from within the needle row and withdrawing also the yarn feed fin ger 29 which, as'shown in Iliff. 1, is carried by the said arm 15. v

When the arm is down in position it is locked by turning the latch into the position shown in F i 3, this turning movement being effected y pressure of the finger upon the projection 27 'libe arm 15 may be adjusted to set the presser wheel in the desired position radially in respect tothe needle row by the screw and slot at 18, 19, and for this purposealso the bracket 23 is'slotted back tothe point 23 to permit the free end of the arm 1.5 to partake of movement during this adjustment.

Adjustment of the resser wheel circumfcrentially of the needle row to set it accul rately in position for pressing the needles is elfectedbyturning the cap or cover 20 which supports the presser carrying arm 15.

- This adjustment is e'ected by means of a .block 28- rota table on the upper reduced end of the post or standard 29f'which, with alike post 29,`ai ds in supporting or sustain-ing the upper structure containing the' knitting elements in proper-position, these posts extending up` from the base .'ng 30 as shown in l`igs, 1 and 2. The turnable block 28'- is grooved or slotted diametrieallv at 31 and a' pin 32 secured to and depending from the web ring 4.

.functions just mentioned. Y

flange of the rap or cover enters this slot, so that by turning the block about thc post 29 the pin 32 will be moved and the cap ad justed circumferentially. adjustment has beei'l made the block can be fixed in position by a set screw 33. It will be understood that only slight adjustment of the inside presser member is necessary.

The system of pressing above described permits removal of the inner presser element so that the machine can be turned around and the needles can be opera-ted without casting off their stitches.

The machine shown is of such small diameter that it has been found imj'naeticable to employ horizontally sliding web holders because their inner ends would nearly or quite meet at the center of the cylinder, which, for illustration, may beonly one-half inch in diameter, and no room would be left for the fabric. The web holders 6, therefore, are pivotally mounted at 34 in a plane considerably lower than their nose ends and considerable distance out beyond the circle in which the nose ends lie, so that these nose ends will move in the arc of a circle, the chord of which is sharply inclined downwardly and inwardly, and as shown the' nose end and the lower projection of the web .lu-rider which ordinarily would constitute the fabric supporting member need n'ot'have any movement beyond the inner surface of the This web holder performs the functions of supporting the newly fed, yarn, while the needle is taking it, thus providing a divisional space between the new yarn and the old loop for pressing; preventing the fabric from rising when the needle advances to take the yarn, and feeding the new yarn in vposition against the needle stem to be taken by the needle beards.

For performing the first mentioned function/i. e. of supporting the new yarn separated from the fabric loo s, the yarn is simly laid on the tops of t e web' holders and needles, preventing it from ballooning and insuring that the beards will seize it, the web holdersare provided with abrupt shoulders 37, the vertical faces ofwhi'ch perform thesupporting presser ring or unit 8 1s pro Reverting to the web holder means, the

When the propel" at points Y or feeding the yarn against the stems of the vided with a rar-liallyslotted enlargement or portion 421 grooved circumferentially at" 34on the webl- 43 to. receive the` trunnions holders. The slotted formation guides the\25 web holders and sustains them laterally. I

The web holders are simply dropped into,

placeand thewhole Series is held 1' n proper working'v position by a guard plate or ring 45 which rests on their upper curved tops,

wise adjusted, bv the pin 'any adJusted position -by of the web holder cage 1l and is held t reby againstlateral displacement. It sheld "down in place by the cap 20.

Any web holder can be lifted out, by removing the coveror or ring 46, thus giving ready access to allthe web holders.

The web holders have their arms 35" f guided in slots between the walls 47 of the cage 11, and .the outer ends of these arms en age' thecam groove or slot 48 of the web .su

o der 'cam ring49, which encircles the cage 11, and lies between said cage and the cap or cover 20 needing no other fastening or support. The presser unit 8 forms also a part of the webholderbed, being slotted to receive and guide the web holders and being `pinnedat 50 to the web holder cage 11. The

web holder cam ring has a in 51 extending out throu'gha notch 52 in tl'ie lower edge of the cap or.- cover 20 and when the cover is turned`to adjust the presser wheel 7 to the proper position circumferentially of the needle row, the web holder cam ring is like- 4For adjusting the web holder cam section 49, Fig, 5, vertically` to4 get the proper throw ofthe web holders, Iprovide a vertically adjustable vcollar 53 onthe post 29', which is adjusted by a nuti 'and held in a set screw 55.` The collar is guided and held against turning by a pin 56 extending down from the ring 57 screwed to the posts 29, 29', said pin passing through the plate 58 on the collar. The collar has pins 59 fixed in per plate passing. through slots 60 in the ring? into the cam section 49* of the web holder cam ring. Now by adjusting the collar vertically' the said cam section vwill be adjusted also. justing movement can move up or down in the notch 52 and in all positions it will hold the web holder cam'ring in 'proper circum. ferential position; I

The described presser' elements can be used 'in straight bar machines.

in which the advanced position of the web close location of' its fabric nose to the verge of the needle cylinder vis illustrated while the wide or large space to receivel the yarn' can lbe seen from the dotted line position 1/ of the web holder.

the desirable funclt hwhich' mightbe obtained withfa wide One of the problems tobe solved in the design of a tape machine with movable web holders, was to present against the fabric at. all times., a web holder surface, that when moving, would not saw, or abrade the yarn. A surface bearing against the fabric and havingeven slightly eccentric movement Would not hold closely tothe fabric all the time, and wouldsawthe fibers and rupture d ric engaging surface is concentric with its pivot and thecontact with the fabric is constant and has themini mum abrasive effect, and the degree of pres` sure is constant for different positions of the web holders. i

The web holder fabric'surface is soarranged Withreference to thecylinder verge,

that the concentric arc cuts the corner'or verge of the cylinder, without variation of extent since it is concentric, therefore -very short loops (the usual requirement) are not The fabric engaging surface ofthe web holder stands at an acuteangle to the needle stem, therefore. as theneedle draws 'new yarn through the'loop the inclined fabric surface assists in knocking over or casting off the old loop. 4' This result has been obtained with sliding web holders, by havingan incline on the web holderl fabric surface, and in action the fabric is raised by the incline and the knockis secured. The upward Aes a wide separation between movement of the fabric is objectional, and the necessary accurate adjustment of web holder cams makes it impracticable.

Thel yarn su porting surface of this improved web holder is concentric with its pi vot.

Owing to the are being atan acute angle to the needle stem, the relative distance from the place where the new yarn rests, and the needle cylinder verge, is very much greater with a narrow bladedwel'i holder, than with a sliding web holder asnsually arranged, unless it has a wide blade. The delivery of the new yarn, from the yarn supporting snr face to the fabric surface `with my web holder, providesa Nery narrow' gap, or space from one surface, to the other for the yarn to snap across, as a small hook is employed, but at the same time a. wide division is provided for pressing: the beards. A wide horizontal blade provides a wide space between the yarn supporting surface, and the fabric surface, Iand the stitches must snap from the high plane to the low plane, unsupported, which causes displacement of the loopsl and causes uneven knitting. My yarn supporting' are surface, presents an acute angle surface to the needle,vand the new yarn is held solidly where it should be, to be seized by the needle hook as the needle descends. `Being a concentric surface, the ram nmveriynt on the web holder is not required .to bencenrately set to keep the yarn at the proper elevation, While.

a sliding web holder having an inclined surface would need to be very nicely adjusted to preserve the perfect alineinent of the in clined surfaces with the needles, and the limit .of the web holders inward movement would be the fabric loops, beyond which the web holder could not go. My yarn supporting surface being 'concentric with its pivot permits of a wide margin of safety in this res ct.

. 1 rom'thc above -it will be seen that I have provided a web holder organization .in Awhich the web holders'are pivotally mounted androek across the needle plane at an acute angle, their fabric tails being buried in lthe needle cylinder'and.presenting' an unchang`- ingr acute angled surface to the fabric loops, the Vinclined fabric hook .having capacity for the new yarn and the old fabric loops, a wide throat measured vertically for receiving` new yarn, and a. small throat opening to hold the knit courses, the yarn supporting surface at the top of the'heok being unchanging in its high )osition relative to theneedlesand serving eeanse of its acute angular relation tothe needle. stems, to'hold the new yarn close to the 'needle stems.

Referring to 10 it will be seen that the housing or cover 20 rests upon an up wurd extension of the ring or )late 57, whichis securedto the posts 29,. 29 extending up against the stemof the. needle- Ais secured to the needle cylinder it will be seen that the needle ei-'linder is' held at its upper end against displacement from its normal position. 'lh'is construction prevents any eccentric or wabblime,` motion at the lop ol the machine. 'lhe needle carrier and the web holder bed with their 'associated parlsmnstitute a single unit or head which is held by the encircling member 2O against wahbling whether the-machine is of the ro` lary ram type or the rotary needle carrier type.
